Filed: 2007-10-09
Abstract: An LCD(Liquid Crystal Display) device and a power supply circuit are provided to reduce a size of the power supply circuit by using a common electrode signal as a driving signal of the power supply circuit and remove the necessity for installing a buffer circuit according as driving capacity of an amplifier for outputting the common electrode signal is big, thereby reducing a circuit area and improving circuit efficiency. A power supply circuit(130) is formed on a TFT(Thin Film Transistor) substrate of an LC panel(100). An output of the power supply circuit is supplied to a vertical driving circuit(120). The power supply circuit comprises a DC-DC converter for generating positive power supply electric potential and a DC-DC converter for generating negative power supply electric potential. The DC-DC converters are driven by a common electrode signal VCOM. The DC-DC converter for generating the positive power supply electric potential outputs VCOMHx2, and the DC-DC converter for generating the negative power supply electric potential outputs VCOMH x -1. Therefore, electric potentials suitable to turn pixel transistors on/off are obtained.

Title: Permutation data transformation to enhance security
Inventor: DAMGAARD IVAN BJERRE
IPC: H04L9/18
Filed: 2005-08-09
Abstract: One data transformation permutes certain bits in a data input based on other bits in the data input. Another data transformation raises one segment of a data input to a power of a function of another segment, the power being relatively prime to a function of a predefined modulus. The modulus is then applied to the result, and the transformed data assembled. In one key derivation application, a segment of the master key is hashed. Two numbers are derived from another segment of the master key. A universal hash function is applied to the result of the hash, from which bits are selected as the derived key. In another embodiment, an encoded counter is combined with segments of the master key. The result is then hashed, from which bits are selected as the derived key. These algorithms can be combined with each other and with key wrapping algorithms or encryption algorithms to enhance the security of these other applications.
